I'd certainly like to see the headphone amp, if it's going to be shown to the public; even build one. Just saying.
Watching with interest.

Most headphones don't need any voltage gain, so I was thinking of something like a B1 with 20 jfets.
Would this be the best design approach or at least a good one?

What a great project! One of the best parts of DIY is impressing your non-technical friends with the fruits of your labor. But this... This is mad scientist DIY! It would impress your technically oriented friends. They would also question your sanity for even attempting such a project. It is truly one of the most fun projects I heard of in some time. I'm excited to see the results.
whazzat with one ( OK - Thousand) hand(s) clapping ?
not good enough in mono .....

Depends, do you want gain on it or not? Because there's a very popular design here (and variations) with which you won't need that many 🙂
Soooooooo,
I'm wondering how things are going on channel #2. Maybe someone might know? Maybe? Hmmmm?

It's slow going. You will see some other project first -
something that you will be able to actually build.

No, unless you want to build a phono stage - and then you need quite a bit more than only jfets.
Have fun, Hannes
Maybe those B2 boards sitting in the corner waiting to make their way into our homes? 😀 😀 😀 😀
My Hafler SE-100 already has about that many Jfets, if you count both the line and phono stages....
Matching 1000 pairs takes time? 😀
Actually I could see a small benefit in not matching as the conductance spread over 1000 pairs could smooth out the x-over non-linearity of the OPS, or what does Mr. Nelson think?

That is true, but the P and N populations would like to be
matched in aggregate. Best to measure each one if you
want perfection - and we do want perfection here, as we
are only doing this once.
